1. slide shrink band over the cap of the container until it rests in place

2. carefully apply heat with a heat gun (hair dryer barely works)

3. move heat source around to ensure the band has been shrunk to a tight fit

It probably won't be perfect the first time, it can sometimes take a few attempts to get the hang of it.

The band must be torn and removed to open the container, once the band has been removed it cannot be reapplied. Shrink bands provide a fast and easy way to offer your customers a tamper evident product.
